Precautions

Before servicing the air conditioning system on any vehicle, please be sure to read all of the following precautions, which deal with personal safety, prevention of component damage, and important points to take into consideration when servicing the air conditioning system:

CAUTION

Air conditioning refrigerant or lubricant vapor can irritate your eyes, nose, or throat. Be careful when connecting service equipment. Do not breathe refrigerant or vapor.

CAUTION

If accidental system discharge occurs, ventilate work area before resuming service.

The air conditioning system uses HFC-134a (R-134a) refrigerant and Polyalkyleneglycol (PAG) refrigerant oil, which are not compatible with CFC-12 (R-12) refrigerant and mineral oil. Do not use R-12 refrigerant or mineral oil in this system, and do not attempt to use R-12 servicing equipment; damage to the air conditioning system or your servicing equipment will result.

Use only service equipment that is U.L.-listed and is certified to meet the requirements of SAE J2210 to remove R-134a from the air conditioning system.

If accidental system discharge occurs, ventilate work area before resuming service.

R-134a service equipment or vehicle air conditioning systems should not be pressure tested or leak tested with compressed air.

Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.

Always disconnect the negative cable from the battery whenever replacing air conditioning parts.

Keep moisture and dirt out of the system. When disconnecting any lines, plug or cap the fittings immediately; don't remove the caps or plugs until just before you reconnect each line.

Before connecting any hose or line, apply a few drops of refrigerant oil to the O-ring.

When tightening or loosening a fitting, use a second wrench to support the matching fitting.

When discharging the system, use an R-134a refrigerant recovery/recycling/charging station; NEVER release refrigerant into the atmosphere.
